Patented Jan. 16, 1906.

Application filed August 5,1905. Serial No. 272,862.

To all whom it may concern:

Be it known that I, ANDREW L. GREEN, a citizen of the United States, residing at Lake City, in the county of Columbia and State of Florida, have invented new and useful Improvements in Bottle-Seals, of which the following is a specification.

'The invention relates to an improvement in bottle-seals of the type designed for ready and convenient connection to the exterior of the bottle-neck.

The main object of the invention is the production of a seal of the type described, which when in proper sealing position on the bottle-neck will be automatically locked in place against removal, the construction being such that a breaking force is required in order to remove the seal-cap from the bottleneck, whereby through the breaking of the lock necessitated in the removal of the seal the unauthorized refilling of the b ottle without notice to the user is prevented.

The invention consists in certain details of.

structure to be fully set forth in the following specification, reference being had to the accompanying drawings, in which Figure 1 is a view in side elevation showing a bottle or jar and a cap constructed in accordance with my invention, the cap being partially broken out and shown in position above the jar. Fig. 2 is a similar view with the cap in place, the bottle-neck and cap be ing shown in vertical section. Fig. 3 is a bottom plan view of the cap.

Referring to the drawings, 1 represents a bottle or ar of any suitable type, the neck 2 of which is externally threaded at 3, as usual. The edge 011 wall of the neckopening is formed at one point with a notch 4, constructed to provide a vertical wall 5 and a sloping lower wall 6, the latter inclining from the base of the vertical wall to the lane of the mouth {edge of the bottle-nee The notch is arranged so that the inclined bottom wall thereof extends in the operative direction of the threads 3 on the neck, as clearly shown in Fig. 1.

The bottle-cap of my construction preferably comprises the ordinary metallic cap 7, having the horizontal disk portion 8, provided with a depending circumferential flange 9, which flange is formed with threads 10, designed for operative engagement with the threads 3 on the bottle-neck. Within the plane of the circumferential flange and depending from the disk 8 I secure what I term a key 11, comprising a metallic strip secured to the under side of the disk of the cap and projecting toward the depending flange, said strip for that portion of its length next the flange 9 being spaced from the disk 8 to provide a latch end 12. By this construction the key is secured to the cap and has an offset or projecting portion extending below the plane of the cap-disk immediately adjacent the depending flange of the cap.

In use the bottle or ar is ordinarily sealed by the usual cork or other stopper 13 and the cap applied to the bottle-neck and screwed into position by engagement of the threads 10 and 3, as obvious. The key 11 is so arranged relative tothe disk of the cap that when said disk is firmly seated against the mouth edge of the neck the latch end 12 of said key will be disposed within the notch 4, with the edge of the latch resting snugly against the vertical wall 5 of the notch. In this position the cap is clearly locked to the bottle, the arrangement of the notch being such that in the movement of the cap to closing position the latch is moving in a direction to cause it to ride over the vertical shoulder 5 and into the notch, resting upon the inclined lower wall 6 thereof, as clearly shown in Fig. 2. As a reverse movement of the cap is necessary in order to detach the same from the bottleneck, and it is apparent that said reverse movement is resisted by engagement of the latch 12 with the key in the wall of the notch, said opening or reverse movement of the cap must be accomplished by the use of force sufficient to break the key from the cap. As the cap is thereby rendered useless for locking connection with the bottle-neck, provision is thus made for guarding the bottle against refilling, as the user finding the cap free for ordinary unscrewing may be at once advised that the original package has been previously opened.

The invention is readily applicable to caps in use and is adapted for threaded connection with a bottle-neck, and the improved cap is intended for use with bottles, jars, or other containing vessels, and though preferably constructed of ordinary sheet metal may be readily manufactured of any other desirable material.

The cap will automatically lock itself when being screwed into sealing position and can not be removed without a force sufficient to break the locking-key from its connection with theicap, and it is to be observed in this connection that said locking-key may be made of various strengths, so as to require but the exertion of ordinary strain to break the tongue or the use of a suitable tool, as maybe desirable in connection with the particular bottle or jar.

Having thus described the invention, what is claimed as new is- 1. The combination with a receptacle having the edge of its mouthformed with a notch,

of a cap arranged for threaded connection with the receptacle and provided with a key to engage said notch to prevent movement of the cap in one direction.

2. The combination with a receptacle having its mouth edge formed with a notch having a vertical wall, of a cap adapted for threaded connection with the receptacle, and a key secured interiorly of the cap and adapted to rest in the notch and against said vertical wall in the cap is in sealing position on the receptacle.

3. A bottle having a threaded neck, the free edge of said neck being formed with a notch, and a cap adapted for connection with the threaded neck, said cap being provided with an interior key to engage the notch with the bottle-neck when the cap has been moved to the limit of its sealing position.

4. A bottle having a threaded neck, the free edge of said neck being formed with a notch having a vertical wall, and an inclined bottom, said inclined bottom extending in the direction of the operative projection of the threads, a cap arranged for threaded connection with the bottle, and a key secured to the cap and adapted to engage said notch when the cap has been screwed to the limit of its sealing position on the bottom of the cap on its sealingmeck.

5. A bottle-cap comprising a disk and a circumferentially-depending flange, and a key arranged radially and interiorly of the cap, said key projecting from the disk portion of the cap adjacent the depending flange.

6. A sealing-cap comprising a disk portion and an integrally-depending circumferential flange, and a key secured to the under side of the disk portion and arranged radially thereof, said key having a projecting portion spaced from the disk adjacent the circumferential flange.

In testimony whereof I aflix my signature in presence of two witnesses.
